Edward,
Most Square D CSED's are only listed for a 100 amp max breaker. If you give me the catalog number of the panel you would like to use I will check the max breaker size.
Doug,
What Edward is describing is pretty normal for our area. We always have a disconnect in the same enclosure with the meter and often have distribution in the same panel too. A meter/main with a 200 amp remote panel is possible but it is often very difficult to run a large raceway or 4/0 SER cable to the remote panel with the way our houses are built. We seldom have basements but when we do they are finished. By having distribution in the exterior panel it makes it easier to add pool, hot tub, and A/C circuits in the future.
